To a/ZZ whom it may concern: 1

Be it known that I, GEORGE H. PERKINS, a citizen of the United States,residingin the city and countyof Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Filling Cans, of which the following is a specification. In filling cans with petroleum it is desirable that the iniiowing stream of oil should be of large size so that the `illing may be expeditiously accomplished, and it is customary to provide the can with an inlet opening of diameter greater than that'of the stream so as to afford an outlet for the air displaced by the oil. In practice, however, it is found thatthe foaming occasioned within the can by the volume and impetus of a large entering stream results in the splashing or overflow of a portion of the liquid through the said air outlet when the level of the oil approaches the top of the can, and renders it difficult to fill the can exactly full. It has been attempted to remedy the difficulty by charging a stream of a given size into a can until the latter is nearly full, and by then partially closing the pipe or conduit through which the stream flows, so that thereafter, the size of the stream of oil iiowing into the can being diminished, the

" amount of foaming within the can will be correspondingly decreased. Such a diminished stream of oil, however, in descending through and issuing from the relatively large vertical pipe through which it flows, does not follow a directly vertical course, but iiows over differentl portions of the inner face of the pipe, and, crawling outwardly across its lower edge, tends to discharge eccentrically and irregularly in different directions, with the result, the pipe not entering the can but terminationg a short distance above it, that a quantity of the oil lodges upon the exterior of the can.

It is the object of my invention to provide an apparatus by which a large volume of oil Amay be rapidly charged to a can or kindred receptacle until the latter is nearly full, and

by which a small stream of oil may thereupon steadily, accurately, and in such manner as not to` occasion foaming or overfiow, be charged to the can untilthe latter is precisely full. p p

In the accompanying drawings I show and herein I describe a good form of a conven- ATENT OEEICE.4 f

ient embodiment of my invention, the particular subject matter claimed as novel being' hereinafter definitely specified.

In the accompanying drawings, Figure 1 is a View inside elevation, and Fig. 2 a central, vertical, partly sectional, elevation, of an oil `reservoir equipped with a good form of my invention. Figs. 3 and 4 are vertical, partly sectional, elevational views ,of my improved oil valve asmounted within the reservoir, illustrating respectivelydifferent positions of the parts.

Similar letters of reference indicate corresponding parts.

In the drawings, A is what I hereinafter term a reservoir, the same being a receptacle of any desired general character, shown however as an upright vessel of cylindlrc contour, the upper end of which is open, andthe lowerend ax of which consists of a depending funnel-shaped bottom having a central discharge opening or mouth, the interior of which bottom tapers from the vertical wall of the reservoir, to a diameter, at its mouth a', corresponding to that of a conduit Bthe npper extremity of which is permanently iitted within said mouth. The conduit B is of any appropriate length, and beneath it the cans to be lled are successively placed with their receiving apertures in alignment with its axis.

D is what I term a reserve funnel, the same being a containing receptacle, adapted to hold a predetermined quantity of oil, contained within and adapted to have vertical movement with respect to the reservoir A. The reserve funnel consists of an open-topped cylindrical body designated dx, having a downwardly tapering bottom designated d, the' lower or exteriorface of which is of such proportions and inclination as to adapt it to accurately and snugly tit within the funnelshaped bottom of the reservoir A. Thetapering bottom d of the reserve-funnel embodies a central aperture cl2, within the lower part of which is fitted the upper extremity of a pipe DX of considerably smaller diameter than, but supported ina position axial with respect to, the conduit B hereinbefore re- I ferred to.

IOO

d is a spider frame mounted upon and se.

the opening in the annular head plate d5.

Upon the valve stem a short distance above its head E, is/formed a boss, enlargement or projection FX., which, in the elevation of the Y said stem, is adapted to encounter the annular head plate and occasion the elevation of the reserve funnel.

The spider d', head plate cl3, and boss FX, constitute a connection between the valve stem and the reserve funnel.

The valve stem maybe operated in any desired manner. The arrangement illustrated in Figs. 1 and 2 of the drawings is, however, adapted tothe purpose and one which I prefer to employ.

G is a windlass wheel having a crank handle g, and mounted with its axis horizontal in such position within the reservoir that its periphery is in line above the valve stem, and Gfx is a flexibleconnection between said stem and windlass. By the throw of the handle g in one or the other direction, the elevation or depression of the valve stein will be occasioned.

In the drawings I have shown the reservoir as provided with an enlargement H to receive the wheel G.

The operation of the device is as follows:- The reserve funnel being supposed in the position illustrated in Fig. 2, and it being assumed that the reservoiris fullof oil and that a can to be filled and adapted to contain a quantity of oil equal to the quantity contained in the reser- Voir, has been placed in position beneath the reservoir, it will be understood that the elevation of the valve stem F will first withdraw the valve head from its seat, and will then, by the encounter of the boss FX with the head plate cl3, lift the reserve funnel from the Ybottom of the reservoir so that the parts will occupythepositionsillustratedinFig.3. Vhen the parts are in such positions, a full head of the oil within the reservoir will be discharged through the conduit B and pipe DX into Jthe can beneath, and the liquid level within the reservoir will be steadily and uniformly lowered. After, however, the liquid within the reservoir has been reduced to the level of the top of the reserve funnel, said liquid level, in the further escape of the liquid, will not be uniformly lowered, for the reason that,-the area of the interior of the reserve funnel being greater in proportion to the diameter of the pipe DX than is the area of the space exterior to said reserve funnel to the diameter of the conduit B,-the level of the liquid exterior to the reserve funnel will fall much more rapidly than the level of the liquid within said funnel, with the result that, after all the liquid exterior to the funnel has escaped through the conduit B, a quantity of liquid will still remain in the funnel to escape onlyT through the relatively small pipe DX.

In Fig. 3 of the drawings the line w-w indicates the liquid level at the end of, say, five seconds after the oil commences to discharge through the conduit B; the line -x In my apparatus illustrated and described herein, by predetermination of the capacities of the reservoir and the reserve funnel with relation to the capacity of the can, the said intermediate level in the can is reached by the oil therein when all the oil in the reservoir exterior to the reserve funnel has been discharged into said can, and, when this condition has been established, as will be understood, the oil remaining inthe reserve funnel,-which is sufficent to complete the filling of the can,-will descend through the small pipe DX alone, in a stream which, although small, will yet be the full .diameter of said pipe DX, and will therefore be discharged directly and accurately through the center of the can opening.

The parts illustrated, as willbe understood, occupy the position shown in Fig. 2 during the operation of charging intoV the reservoir the oil or other liquid to be subsequently charged to the can, the valve and reserve funnel being so related to each other,-and the reserve funnel so related to the bottom of the reservoir, that a liquid-tight closure of the bottom of the reservoir is effected. After a can has been placed in position beneath the reservoir,-the valve stem F is, by the throw of the handle g, elevated, and in its elevation, operates first to withdraw the valve head from its seat within the outlet of the reserve funnel, and, second, by the encounter of the boss F with the annular head plate, as shown in Fig. 4, to elevate the reserve funnel to the position illustrated in Fig. 3, to allow of the discharge of the oil at first through both the conduit B and pipe DX, and, subsequently, after the intermediate liquid line in the receiving can has been reached, through the pipe DX alone. A
